HEADLIGHT.

, Application filed April 11, 1923. Serial No. 631,277.

To all whom it may concern:

Be it known that I, BnRNARnHANsoN, a citizen of theUnited States, and a resident of Martin, Ottawa County, and State of Ohio, have invented a new and useful Headlight, which invention isfully set forth in the following specification.

This invention relates to certain new and useful improvements in headlights and the primary object thereof -is to provide imiroved means for overcoming the objectionthe rays projected by thelights and wherein the light rays will be projected parallel to the horizontal or at an angle below the horizontal.

A further object of the invention is to provide an inclined reflector and novel 0 crating means therefor, by means of whic the light rays projected vertically by the lamp, are intercepted by the reflector and then horizontally projected through the usual vertically disposed lens of the headlights.

Another object of the invention, is to provide a reflector which spreads the light rays laterally so as to effect illumination of the sides of the road and to alsp'provide a reflector of novel form and construction so as to increase the reflecting power thereof.

A further object of the "invention is to' provide novel and improved means forretaining the lens in position, while still permitting of easy and quick removal-and posi tioning thereof, 1

Still another object of the invention is to provide novel means for connecting and mutually bracing the two headlights which means serves to house or protect the parts that effect simultaneous operation of each of the two reflectors.

The invention has still further and other objects which will be later set forth and manifested in the course of the following description.

Inproceeding in accordance with the present invention, a Vertically disposed casmg 1 is employed having a parabolic re flector 2 and'a'light bulb 3 therein. The re,v flector 2 is held in position by means of bolts 4, which latter also act to hold bar 5 in its position extending diametrically across the upper end of the casing 1. -The'bar 5 supports semi-circular light intercepting shields or members 6 and 7 The reflector R is composed of plates 8, 9 and 10, that are each formed with flanges 11 which abut and which are riveted together, as depicted in Figure 15 of the drawings, the outer plate 10, bein formed with perforated ears 12 secured y bolts 13 to a bar 14, which latter in turn is secured by bolts "15 to the lens casin 16. The reflector plates are of ovaloid or liptical form, the central one 8 being curved upwardly toward a line 17- extending axially of the-ellipse as indicatedin Figures 14, and 15 to spreadthe rays of light.

The lens casing has a neck 18 and has the v front thereof provided with a lens 20, while the rear upper end of the neck thereof is inclined as indicated at 21. The lens 20 is-held against the inturned edge 22 of rim or outer ring 23 which latter has pins 24' enga ed by curved spring fingers 25, the latter ormed on the" free edge of the casing 16, the casing 16 having a channel 27, one wall of which h l ts 28 to admit th p Ang e c ps 29 are riveted to an inner ring 30 which latter has a channel receiving a circular packing or cushioning ring 31. D The clips 29 have corrugated 'parts 32 which not' only rod 34, the outer end of the rod having ad-v justins nuts against which the perforated end 0 the arm 33 is held by a coil spring 36. The inner end of the rod 34 is pivoted between the ends of an arm 37 carried on a rod 38, the rod 38 bein turnably mounted in a bracket 39 attached to the lens casing 16. The.brack et 39 has a toothed or segmental rack 40 the teeth of which are en gaged by a tooth 41 carried by the arm 37. The rod 38 is tensioned by a sprin 42 coiled thereabout and abutting a part of the bracprojects through the instrument board 47..

The inner end portion of the rod 45 slides through a bracket 48 that is carried by the frame of the machine. The rod 45 is preferably mounted in a flexible sleeve 49-to prevent rattlin Referring to igure 1 of the drawings it will be seen that the brackets 39 are attached to the inner 'sides'of the lens casing 16 adj acent to the upper arcs or ends'of the latter, and have projecting shanks 50 to whichthe ends of an angle plate or bar 51 are secured, the angle bar serving to brace each of the headlight casings and further serving to house a rod52, which latter corresponds to the rod 38 of the companion headlight, the rods 38 and 52 being connected to the arm 43 so that movement of the latter will effect simultaneous movement of each of the arms 34 and thereby the reflectors in the lens 1 casings; of the two headlights.

It will be understood, of course, that the above described parts, excepting arm 43 are the same in each of the headlights, the arm 43 being common to each and affording a common operating means accordingly.

Inoperation, it will be seen that the light rays eminating from the bulb 3 are projected vertically and are intercepted by the shields 6 and 7, so as to intercept the rays of the direct cone of light that would be reflected by the reflector above the horizontal. The

light rays being intercepted by the reflector will be reflected through the lens 20 parallel to the horizontal or at an angle below the horizontal, depending upon the'inclination of the reflector. Thie light rays are spread through the arms 33 cause movement of the respective reflectors about their pivotal points 13. The spring 42 serves to hold the tooth 41 of arm 37 in engagement with the teeth of the rack 40, thereby holding the reflectors in any position to which they may be moved. The spring 36 acts to cushion the movement-of the reflector in changing the angles of inclination of the latter.

In order to remove the lens from its casing, it is merely necessary to turn the ring 23 to cause the pins 24 thereof to register with the slots 28, whereupon the ring 23 can be moved outwardly, carrying with it the lens 20 and enabling the ring 30 to be then removed. Y

l-Vhat is claimed. is I 1. In combination with a pair .of headlights each having a casing with a pivoted reflector therein, a bracket carried by-each casing and having inner and outer parts which project into and'out of the casing, an angle bar connected at its ends to the respective outer parts, a pair of shafts journaled in the brackets and housed by the angle bar, racks carried by the inner parts, the ends of the shafts adjacent tothe racks having racks, springs on .the shafts to tension same to hold said arms engaged with the racks, means connected to the arms and to the reflectors to actuate the latter, and means common and connected to each of the shafts to actuate same in unison.
